Allergic reactions to the common house plant Hoya compacta (HC) have not previously been described.
To confirm HC as the cause of rhinoconjunctivitis in three horticultural workers.
Greenhouse working conditions were reproduced in our challenge chamber.
All three cases developed rhinoconjunctivitis when working with HC plants. A control challenge was performed in two cases with iceberg lettuce causing no symptoms. Nasal volume measured by acoustic rhinometry (AR) fell after all three active challenges, but also after one of the control challenges.
Our study confirms that HC may cause occupational rhinoconjunctivitis and asthma through a Type I hypersensitivity reaction. Specific inhalation challenges, nasal nitric oxide measurement and AR may be useful additional tools in supporting such diagnoses for occupational physicians to consider.
先前并未描述过对常见室内植物合果芋（Hoya compacta，HC）的过敏反应。
确认 3 名园艺工人的鼻结膜炎是由 HC 引起的。
在我们的挑战室中再现温室工作条件。
与 HC 植物一起工作时，所有 3 例均出现鼻结膜炎。在 2 例中进行了生菜对照挑战，没有引起症状。鼻声反射测量（acoustic rhinometry，AR）的鼻腔容积在所有 3 次主动挑战后以及在 1 次对照挑战后均下降。
我们的研究证实，HC 可能通过 I 型超敏反应引起职业性鼻结膜炎和哮喘。特定的吸入性挑战、鼻一氧化氮测量和 AR 可能是支持职业医生考虑此类诊断的有用附加工具。
